 The fossil stilt-legged fly ""Electrobata" tertiaria" from Baltic amber of the Paleogene also shows some similarities; it may be a very basal member of the Metopochetini, close to the divergence between these and the Eurybatinae.Apart from its lack of wings and halteres, "B. ambulans" has a less unusual habitus than other members of the Micropezidae.Its body is stockier, with a petiolate abdomen (like in ants and other Apocrita), its middle and hind legs are less elongated, and its forelegs are less shortened than in its relatives.
